Confirmation - error in process - idoc status 29

HI ,

i got one new problem today.

This is one of the case when one user createsconfirmation of the Purchase order and then Confirmation status goes to error in process. i check in RZ20 and found error in Idoc which is generated from that confirmation,When i check the status record it says error in ALE.status 29. Only an inactive partner profile was found with the following key and this is my PRDCLNT100 (production system address).

I can see that all other confiramtions are getting posted but having an issue with one confirmation.

2ndly how i can delte error in process Confirmation . So that we can create new confirmation , or is there any other way to get my present confirmation status to Posted.
